Overview

This page summarizes how the City of Yorba Linda's Zoning Code regulates land use (the local ordinance is codified in Title 18, the "Zoning Code") and where to look for the rules that control permitted uses, conditional uses, and the dimensional standards that apply to each district. See the city's planning overview for context on how zoning fits with the General Plan. The code requires you to consult the Land Use Matrix and the zone chapters to determine whether a use is Permitted, Conditional, Accessory, Temporary or Prohibited (see § 18.08.070) .

Notes up front: the city uses chapter/§ citations in the Zoning Code (e.g., § 18.10.020), not a separate "Title 17." When the code refers to development standards, it calls those out in tables (for example Table 18.10-02 for residential standards) — consult those tables for front/side/rear setbacks, lot size, lot coverage and height limits (see § 18.10.090 and Table 18.10-02) .

District-by-district breakdown

Below are the most decision-relevant Yorba Linda base zones. Each subsection gives the stated purpose, typical permitted uses, key dimensional controls and where the zone is applied in the Code. For use-permission logic the controlling references are the master Land Use Matrix (Table 18.08-1) and the abbreviated tables under each chapter; when a use is not listed it is treated as prohibited unless the Community Development Director determines otherwise per § 18.08.060 .

R-A (Residential Agricultural)

  • Purpose: conserve agricultural and low-density residential land; large lots and farm/ranch uses are expected. See § 18.10.020 for intent and basic lot/density approach .
  • Typical permitted uses: single-family dwellings, farming/ranching (commercial and noncommercial), accessory farm structures, limited home occupations — consult Table 18.10-02 and the Land Use Matrix for specifics (see § 18.10.090 and § 18.08.070) .
  • Key dimensional standards (code-controlled): Minimum lot size 1 acre, maximum density 1.0 DU/acre; minimum lot width and depth appear in Table 18.10-02 (see § 18.10.090) .
  • Where it applies: used where the General Plan designates low-density/agricultural land; refer to the official zoning map (filed with City Clerk) per § 18.08.030 .

R-S (Residential Suburban) and R-U (Residential Urban)

  • Purpose: R-S is medium-low density suburban lots; R-U is higher suburban/urban single-family density with smaller lots and tract-style neighborhoods. See § 18.10.010 and the zone descriptions in § 18.10.020–.080 .
  • Typical permitted uses: single-family homes, accessory dwelling units (ADUs where allowed), small home-based businesses consistent with home occupation rules; transitional/supportive housing is treated as a residential use and is permitted in residential districts consistent with the same standards (noted in the Land Use Matrix) .
  • Key dimensional standards: see Table 18.10-02 — examples include minimum lot size 10,000 sq ft (R-S) and 7,500 sq ft (R-U) and maximum densities 3.0 DU/acre (R-S) and 4.0 DU/acre (R-U); front/side/rear setbacks and lot width specifications in the same table (§ 18.10.090) .
  • Practical note: front setback averaging for subdivisions is allowed (reduction of up to 25% on individual lots provided the development average meets minimum) — see § 18.10.100.A.3 .

R-M, R-M-20, R-M-30 (Multi-family residential and higher-density multifamily)

  • Purpose: allow garden apartments, townhouses, stacked condominiums and higher-density housing types; each has a stated maximum density (10, 20, 30 DU/acre respectively). See § 18.10.070–.072 and Table 18.10-02 .
  • Typical permitted uses: multi-family dwellings, clustered single-family in some R-M areas, associated common open space and recreational amenities; supportive/transitional and small employee housing are specifically addressed in the Land Use Matrix as permitted where configured like other residential uses (§ 18.10.090 / Land Use Matrix) .
  • Key dimensional standards: maximum densities are explicit (10 / 20 / 30 DU/acre), minimum lot sizes vary (see Table 18.10-02) and building separation rules and special height/setback rules for buildings over 15 feet apply (see § 18.10.100.A.1 and Table 18.10-02) .
  • Where it applies: mapped where General Plan identifies medium-high and high-density residential; consult official zoning map and Table 18.02-1 General Plan/Zoning consistency table .

C-O, C-N, C-G (Commercial - Office / Neighborhood / General)

  • Purpose: C-O for offices and professional uses compatible with nearby residences; C-N for neighborhood shopping; C-G for broader retail/wholesale commercial. See § 18.12.020–.040 and the commercial Land Use Matrix Table 18.12-1 .
  • Typical permitted uses: retail/service businesses (varies by subzone), restaurants and offices — many uses are conditional in C-N or C-G and some are prohibited depending on zone; see Table 18.12-1 for exact per-use permissions. Examples: Retail/service business = P in all commercial zones; Restaurant = C in C-O/C-N/C-G per Table 18.12-1 .
  • Key dimensional standards: Table 18.12-2 sets minimum lot sizes, front/side/rear setbacks and maximum lot coverage (for example minimum front setback 25 ft in several commercial zones and lot coverage 35–60% depending on zone) — see § 18.12.060–.070 and Table 18.12-2 .
  • Special constraints: when a commercial lot adjoins a residential zone, a 50 ft minimum setback is required unless otherwise approved (see § 18.12.070.A); outdoor uses, car washes and other higher-impact uses frequently require conditional use permits and additional studies (acoustic, circulation) as the code states .

OS / OSR (Open Space / Open Space Ranchettes)

  • Purpose: preserve natural resources, low-intensity recreation, and limited private use; OSR permits limited residential ranchettes at very low density. See § 18.16.400–.420 .
  • Typical permitted uses: agriculture/farm/ranch, wildlife preserves, limited public recreation; many active uses are conditional or temporary — see Table 18.16-6 (Open Space Land Use Matrix) for the per-use designations (P, C, A, T or prohibited) .
  • Key dimensional standards: Open space development standards appear in Table 18.16-7 and lot/density limits are described in the OSR zone text (e.g., minimum lot sizes of five acres and maximum density 0.2 DU/acre for OSR) — see § 18.16.420 and Table 18.16-6/7 .

PL (Presidential Library)

  • Purpose: special-purpose district for the Richard M. Nixon Presidential Library campus and supporting cultural uses; the code provides its own Land Use Matrix and development standards. See § 18.16.300–.320 and Tables 18.16-4 and 18.16-5 .
  • Typical permitted uses: the presidential library and museum are permitted uses; many related uses (conference center, performing arts, restaurant as accessory) are conditional or accessory — see Table 18.16-4 for specifics (e.g., Presidential library = P, Performing arts center = C) .
  • Key dimensional standards: Table 18.16-5 lists standards such as 50 ft street-facing setback, maximum building height 35 ft / 2 stories, maximum building coverage 35%, and parking ratios (e.g., 1 space per 300 sq ft GFA) — see § 18.16.320 and Table 18.16-5 .

Other districts & overlays (summary)

  • M-1 (Light Manufacturing) and PD / PS (Planned Development / Public & Semipublic) and MHP (Mobile Home Park) appear in the General Plan/Zoning consistency table; consult Table 18.02-1 and the chapter for the applicable development rules .
  • Overlay and combining zones (e.g., Imperial Highway Combining Zone referenced as (I)) appear in the code and carry special rules; see the zone-specific chapters and the overlay chapter for how those modify base zone permissions. For overlay specifics consult the city's overlay districts page and the code references to "(I)" uses in the commercial Land Use Matrix .
  • If you expect to rely on an interpretation (is this use similar to a listed use?), the Community Development Director has interpretive authority and may refer matters to the Planning Commission under § 18.08.060 .

How to read permission codes in the land-use tables

  • The Land Use Matrix uses letters: P = Permitted Use, C = Conditional Use (requires Use Permit), A = Accessory, T = Temporary, • = Prohibited and D indicates Design Review is required. The master matrix and the abbreviated zone tables are controlling; see § 18.08.070 and the legends in each table for the meaning of codes .

Checklist — what an applicant must verify/prepare before filing

  • Confirm your parcel's base zone on the official zoning map (filed with City Clerk) and cross-check with Table 18.02-1 (General Plan/Zoning consistency) — see § 18.08.030 and Table 18.02-1 .
  • Check the Land Use Matrix (Table 18.08-1) and the abbreviated table for the zone to see if your intended use is P, C, A, T or • (prohibited) — see § 18.08.070 .
  • If the use is C, prepare a conditional use permit application and any required technical studies noted in the zone chapter (noise, circulation, landscaping, screening) — see commercial special requirements § 18.12.070 and OS special requirements § 18.16.440 .
  • Prepare plans showing compliance with Table 18.10-02 (residential) or Table 18.12-2/18.16-5 (commercial/PL/OS) for setbacks, lot coverage and height — see § 18.10.090, § 18.12.060, § 18.16.320 .
  • Calculate parking per the off-street parking chapter and include in submittal (see Chapter reference in each development standards table) — chapter referenced in tables as Chapter 18.22 (see commercial/residential tables) .
  • If design review is required (table indicates D or chapter references design review), follow the design review submission requirements — see design-review references in the tables and Yorba Linda Design Review .
  • If you intend to rely on an interpretation (use not listed), submit a written request to the Community Development Director — see § 18.08.060 .
  • Pay attention to special zone notes (e.g., setbacks adjacent to R zones, viewscape provisions, trails/easements) found in the special requirements for each chapter (e.g., § 18.12.070, § 18.10.100, § 18.30.050) .

Risks & Ambiguities

Issue Why it matters What to verify
Is a proposed use "similar" to a listed use? The code treats unlisted uses as prohibited unless the Community Development Director determines similarity; divergent interpretations can delay projects. Verify with Director; request written interpretation per § 18.08.060 and be prepared to appeal or take matter to Planning Commission .
Overlay/Combining zone provisions (Imperial Hwy (I), etc.) Overlay rules can change whether a use is allowed or whether additional conditions apply (Table notes use (I)). Check overlay chapters and the official zoning map; confirm whether the (I) or other overlay applies to your parcel (see Table 18.12-1 notes) .
Which table controls if different tables appear? The master Land Use Matrix and the abbreviated zone table both apply; conflicts need interpretation. Use § 18.08.070 guidance and consult Community Development Director for controlling interpretation; always cross-check the zone’s chapter table and Table 18.08-1 .
ADU applicability and standards ADUs are referenced as accessory in some tables but State ADU law may override local limits; misreading can cause noncompliance. Check the ADU-specific chapter and state ADU law; local ADU notes in the Land Use Matrix and accessory use entries; verify with the city's ADU guidance and the code citations (ADU references in use tables) — if not explicit, consult staff (Verify with the jurisdiction). Not found in retrieved materials: a consolidated ADU ordinance text in these files. .
Parcel-specific exemptions or tract map conditions Approved tract/parcel maps or vesting maps can carry different rules or grandfathered rights. Review any recorded tract/parcel map conditions and check § 18.02.040 for how older approvals interact with the current code .

Plain-English Summary

Yorba Linda's zoning code (Title 18) lists which uses are allowed in each zone via a Land Use Matrix and zone-specific tables; check your parcel's zone on the official zoning map, then read the abbreviated table and the development standards table for that zone to learn whether a use is Permitted, Conditional or Prohibited and which setbacks, lot sizes and parking rules apply (see § 18.08.070, Table 18.10-02, Table 18.12-2, Table 18.16-6). For unclear cases the Community Development Director can interpret whether a use is allowed; conditional uses require a Use Permit and often technical studies (noise, parking, landscaping) — verify specifics with the Community Development Department (Verify with the jurisdiction) .

Frequently asked questions

What can I build on an R-1 lot in Yorba Linda?

The Zoning Code's residential tables control R zones — consult the residential Land Use Matrix and Table 18.10-02 for the specific permitted uses. In general single-family dwellings and typical accessory uses are allowed; any use not listed is prohibited unless the Community Development Director finds it similar under § 18.08.060 .

What are Yorba Linda setback requirements for single-family homes?

Setbacks are specified in Table 18.10-02 and additional setback rules (e.g., for buildings over 15 ft or front set-back averaging) are in § 18.10.100. Check the Table 18.10-02 row for your specific residential zone (R-A, R-S, R-U, etc.) for front/side/rear numbers .

Do I need a conditional use permit for a restaurant in a C-N zone?

Restaurants are shown as a conditional use in several commercial zones in the commercial Land Use Matrix (see Table 18.12-1) — if the table marks C for the C-N zone, you will need a conditional use permit and any studies the permit requires (noise, parking, etc.) as noted in the chapter § 18.12.050–.070 .

Where is the master Land Use Matrix and which table controls?

The master Land Use Matrix is Table 18.08-1 (included as an attachment to Title 18) and abbreviated tables appear in each zone chapter. Both the master matrix and the zone-specific table are controlling; read § 18.08.070 for instruction and consult the specific zone chapter tables for details .

Can I run a home-based business/dashboard business from an R-U lot?

Home occupations and small home-based businesses are treated as accessory uses in residential zones in the Land Use Matrix (often marked A); refer to the home-occupation rules in the code and the R-U abbreviated table. If the business is higher-impact, it may be prohibited or require a different zone or a permit — consult § 18.10.090 and the Land Use Matrix and seek an interpretation if unclear .

How does the code treat transitional or supportive housing?

Transitional and supportive housing are treated as residential uses and are permitted in residential zones subject to the same standards as similar residential configurations (noted in the Land Use Matrix and in Table 18.10-02) — see the Land Use Matrix notes and § 18.10.090/related table notes .

If my lot borders a residential zone, are there special commercial requirements?

Yes — a minimum 50 ft setback is required where a commercial (C) zone abuts a residential zone unless otherwise approved; see § 18.12.070.A for the commercial special requirement that protects adjacent residential properties .

Where are ADUs shown in the code and are they allowed everywhere in residential zones?

ADUs are shown as accessory uses in the Land Use Matrix for some residential zones (the tables include ADU/accessory dwelling references). The code also cross-references a separate ADU chapter or state law; check the accessory-use entries in the zone table and consult the city's ADU guidance and state ADU law (Verify with the jurisdiction) — not all ADU-specific parameters appear fully consolidated in the retrieved materials here .

If a use is not listed in the table, is it automatically prohibited?

Yes — the code states "Any use not included shall be considered prohibited" in the zone tables, but the Community Development Director can interpret similarity to a permitted use under § 18.08.060; such determinations are written and can be appealed to the Planning Commission .

How do I confirm the exact zone and overlays affecting my parcel?

Check the official zoning map (kept on file with the City Clerk and the Community Development Department) and the General Plan/Zoning consistency Table 18.02-1; overlay/combine zone notes appear in the land-use tables (e.g., (I) for Imperial Highway Combining Zone) and you should confirm overlay applicability with staff per § 18.08.030 and Table 18.02-1 .
